Claims

[Scope of utility model registration request]

A rotary actuator that rotates a rotor by supplying pressure fluid into a pressure chamber limited to one side of a plurality of blades of the rotor and discharging fluid in the pressure chamber limited to the other side. A rotary actuator characterized in that a fluid flow path that communicates the pressure chambers with each other and a fluid flow path that communicates the pressure chambers on the other side with each other are provided in a side plate on which the side edges of the blades slide.
